Tid- och resursplanering ? En utvärdering av verktyg för projektplanering.

Den projektbaserade arbetsformen blir allt mer vanligt förekommande inom alla nivåer i samhället. Projekt kräver planering, bland annat tid- och resursplanering. Tid är en av de viktigaste beståndsdelarna i projekt, och tidsaspekten är av avgörande betydelse om projektet kommer att lyckas i sin helhet. Resurser är en annan viktig beståndsdel som också har en avgörande betydelse om projekt kommer att nå målen. Samtidigt som projektet som arbetssätt tilltar, tenderar projekten att växa i storlek.

Development of a method for determination of pesticide residues in honey using liquid chromatography tandem mass spectrometry

Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.

Tillämpning av utvärdering inom operativt förbättringsarbete

In the fall of 2014 a literature review and a scientific study of the topic; "... in the extent to which companies in the industry applies the evaluation of continuous improvement? was conducted at Mälardalen University. These studies are the foundation of this thesis.A strategic improvement is often divided into smaller steps of improvements at each hierarchical level from the top down through the organization. But if there is no response system that can confirm the results of these improvements back through the organization it is very hard to see if the improvements really are improvements or just changes and a waste of resources.

Stereoseende i realtid

In this thesis, two real-time stereo methods have been implemented and evaluated. The first one is based on blockmatching and the second one is based on local phase. The goal was to be able to run the algorithms at real-time and examine which one is best. The blockmatching method performed better than the phase based method, both in speed and accuracy. SIMD operations (Single Instruction Multiple Data) have been used in the processor giving a speed boost by a factor of two..

This study was done with the goals of investigating and determining existingsurfaces due to the frictional force and leakage. How can we in an easy mannerdescribe these?A number of ten front forks were part of a main study.

Analys av linjetaxering i samband med gallringsinventering med avseende på kvalitet, tillförlitlighet och framtida utformning

Modern forest owners are very familiar with forest management and forest economics. Therefore they have high demands for quality in forest operations. Guarantee of quality in the shape of self-checking activities is an important tool to guarantee a well managed forestry operation. To meet the forest owners? demands on guarantee of quality and the entrepreneurs wish of an easy method for self-checking, the forest owners association, Södra skogsägarna, has developed a new method for thinning inventory. The purpose of this study is to evaluate the method that is used for self-checking and to find ways to develop and improve of the method. The data has been collected by inventory in a number of stands with circle-area survey and with strip survey, which is method that is used for self-checking. The results show that the strip survey does not diverge more than ±10 % in measuring values of basal area, number of stems, roads share, thinning quotient, outtake of basal area and total volume compared to circle-area survey.

Unified Flow Sensor

Value stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value stream mapping on the planning part of the company is lacking because the method is relatively new.In this work, a comparison is made between the introduction of value stream analysis on production and planning.

Texturbestämning genom fält-, pipett- och hydrometermetoder :

Texture is an important soil property and accurate particle size analysis of soil texture is therefore crucial. There are a number of well-established and newly developed methods available for determining soil texture. In order to compare the results of these methods, the differences between them must be determined. The difficulties, problems and differences regarding texture class determination were examined through a study performed on forest soil samples. The study compared different methods (pipette, hydrometer and field methods) and two types of dispersing agents (sodium pyrophosphate and sodium hexametaphosphate (calgon)) commonly used for particle size analysis.

Ideellt engagemang och inställning till arbete

This Master´s thesis aims to aquire knowledge about volunteers attitude toward work. It emphasis is on the differences between volunteers and non volunteers. There are four research questions used in order to fulfill the aim in a scientific manner. The essay aims to get in depth knowledge regarding whether or not the respondents feel that they have gained advantages in work life due to the fact that they are involved in volunteer work. One of the pivotal questions is if there is a possibility to see a pattern that binds together the reasons for volunteer work and the attitude toward work.

Utvärdering av substrat för biogasproduktion

The purpose of this study was to evaluate the different substrates that enter the digestion on Sundet wastewater treatment plant for production of biogas.This work have done an analysis of data about the biogasproduction from January 2012 to feburari 2013, this showed that the food substrates has a greater gas production than internal sludge.Through laboratory test the VS, TS and COD values for all the substrates used in the biogas production could be determinded. But the COD-method was less optimal for analysis of fat and food, therefore it optimized the method for fat but due to time constraints, this could not be done on the food substrates..

Förhöjd kompetens eller välling i hjärnan?

The purpose of this study was to examine if women's career was affected by becoming a mother after 35 years old. It was also our intention to discover if it was an intentional or an unintentional choice to postpone giving birth just for the sake of the career. We have read articles that are implying that women´s career possibilities, combined with children, is difficult and of current interest in today's society. Science has shown that it no longer appears to be women's main life objective to give birth but they now also wants a career. We wanted to shed some light on the subject from two different angles, so we looked both from the women's perspective and from the employer's perspective.

Föräldraledighetens påverkan på mäns hälsa. En litteraturbaserad studie om sambandet mellan pappaledighet och hälsa utifrån riskbeteende och maskulinitet.

Introduction: Although life expectancy had increased in Sweden for many decades and several health problems had diminished over time, there was no change in men's risk behaviour regarding for instance high alcohol and tobacco consumption. Many of the gender differences in health that existed in society explained were due to power structures and beliefs about behaviour based on gender; a social construction that resulted in the relatively high valuation of men with a more masculine behaviour. Aim: This literature review aimed to study and identify the scientific knowledge regarding paternity leave and its impact on men's health. Method: A literature- based study design was used and the material consisted of peer-reviewed articles from which six themes were identified: alcohol, tobacco, stress, isolation, social support and mortality risk. Results: Divided into three parts, the results described the socioeconomic background of the men who took paternity leave, as well as the impact of paternity leave and masculinity as an impact on men's health.

Anestesi och intensivvårdssjuksköterskans hantering av mekanisk ventilation : - en litteraturstudie om minskning av atelektasbildning och förebyggande av komplikationer

Background Atelectasis is a commun respiratory complication related to general anesthesia and may contribute to pneumonia and acute respiratory failure. Atelectasis apear within 10 minutes after anesthetization and occur in 90% or more anesthezied patients regardless of age and gender. The aim of this study was to indentify if there are any evidence for which methods are ultimate or are most efficacious to reduce and prevent the formation of atelectasis.                                                                                                          Methods This study is a descriptive litterature study where 28 scientific studies have been indentified for review and analysis.                                                                                                               ResultsThe use of 100% oxygen during the induction of anesthesia favors the developement of atelectasis. This can be prevented by preoxygenation with oxygen content of 100% combined with a PEEP of 6-10 cmH2O. When free airway is secured, oxygenation with 100% was found to be unnecessary.
